My suggestion is to use a Jupyter notebook or Google Colab notebook together with a browser marker plugin. You can't quite type anywhere; but you can inline or center the latex per usual. I use chrome with a free app called "page marker" that lets me draw on any window in chrome, whether that's my Jupyter notebook or a Colab one.
